To all whom it 11mg; concern: iliary cylinder cooperating with the folding- Be it known that we, WALTER 8. BROWN cylinder and adapted to cut the paper at preand HENRY W.

Furthermore, it

will be obvious that the parts 17 and 18 desi nated as belting," are mere tapes, and t eir office is to cooperatively carry and deliver the articles, such as envelops, as before explained, first onto the periphery of the rotating folding-cylinder 2 and thence into the s ace immediately between said cylinder and the vertical section 19 of the paper which has beenfolded longitudinallyuponitself through the mediation of the tapered nose 20 and the cooperating rollers 21 and 22 common to some forms of rinting-presses. The longitudinally-folde paper web then passes between the cylinder 2 and the cutting-cylinder 3 and is then fed between the cylinder 2 and two rolls 43, and simultaneously with the cutting of the web by the cylinder 3 the tumbler 44 assumes a position above the pass between rolls 43. When the paper web travels around the cylinder 2, the envelop which has been fed between said cylinder and the web is carried therewith, so that when tumbler 44 arrives in the ositi on indicated in 5 the web will be olded upon itself, as shown at 45, and will be fed between rolls 43, thereby carrying the envelo between the folds, asshown at 46. Said fol ed web and the envelop therein are then carried into position above rolls 47, where the web is again folded by means of a plunger 48, and the envelop is thus securely incorporated within the folds of the web and cannot be easily removed therefrom except by unfolding the paper. This apparatus for folding the web does not constitute any portion of our invention, but is merely one of a number of means utilized for folding paper webs.

In F' 4 we have shown a bundle or stack of enve ops, which we have designated by the numeral 23, said envelops being held in tact, one upon another with flaps downward, by any suitable means, as the vertically-disposed rods or wires 24, secured in sockets provided in the adjustable members 25, and in order to successively feed the envelops into cooperation with the tapes or belting 17 and 18 we provide upon the rock-shaft 26 a pair of fin ers 27, which are suitably curved, so that t eir free ends may be moved upwardly and outwardly until the ends thereof are brou ht into enga ement with the depending ap 28 upon t e lowest envelop, and it therefore follows that when the said fingers 27 are again moved inward they will engage said flap and draw the bottom envelop inward and downward and deliver it into a place between the rollers 10 and 14, and as said wheels and tapes or belting carried thereon are properly rotated the envelop will be delivered to the tapes and carried downward thereby onto the periphery of the cylinder and by the cooperation of the ta e or belting 18 it finally will be delivered etween the printed paper and the cylinder, as before explained. order that only the bottom en- I i i velop be drawn inward by the action of the fingers 27 we have provided the flexible stop 29, which is referably made of rubber and slightly beve ed, as clearly shown in Fig. 4. This stop is positioned so 'aI F-to allow but one envelop to pass under it, and it yields to any pressure placed thereon incident to the inward movement of the lowest envelop, but immediately assumes its normally vertical position when such force is removed.

By reference to Fig. 2 it will be observed that the rock-shaft 26 is mounted in suitable bearings 30, carried by the framework, and

is actuated by means of the slotted arm 31,

rigidly secured to the outer end thereof, as by the set-screw 32 or equivalent means. The slotted arm 31 is connected with the source of power b means of the link member or bar 32, cxten ing downward into engagement -with the wrist-pin 33 upon the disk-like member 34, attached to the gear 35 upon the shaft 36, it being understood that said gear is placed in mesh with the gear 37 on the end of the folding-cylinder 2, said gears being of proper size to secure the requisite movement of the shaft 26, whereby the movement of the fingers 27 will be properly timed for the performance of their office in successively delivering the envelops into engagement with the tapes, as before mentione As an auxiliary means for mounting our attachment 4 in proper position we loosel mount upon the shaft 26 a bearin 38,whic is adjustably secured by means 0 screws 39 within a bracket 40. This bracket is fastened to the frame of the press and serves to give the shaft 26 a very firm support.

In addition to the support for the envelops afforded b the standards 24 we have also provided the lates 41, which are curved at their inner en s to correspond to the guidin plate 42, said parts cooperatin with eac other to provide a guideway for tTie envelops, &c., to be delivered into each paper.

It will therefore be observed that our feeding mechanism is entirely automatic in its operation, all that is required from the attendant being to rovide a supply of envelops or other artic es which it is desired shall be delivered into the folds of the paper at the instant the latter is received by the folding mechanism.

Inasmuch as various modifications and changes may be made in the construction and combination of elements deemed necessary in materializing our invention, we do not wish to be confined strictly to the exact showing herein made.

Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. The combination with the folding-cylinder of a printing-press, of an euvelop-car rying belting or tape; an auxiliary belting cooperating therewith and with the periphcry of said cylinder and devices for successively deliverin an envelop, folder or the like between said cooperating tapes, snlistan- Fall as specified and for the purpose set ort 21 The combination with the folding-cylinder of a printing-press, of a suitsbleframework attached to the framework in which said cylinder is mounted; a pair of shafts each having a band-wheel; a pair of arms or brackets each havingan idler or ta e wheel to co- 0 crate with its respective w ieel upon said s iafts; suitable means for actuating both of said shafts whereby the belting on each pair of wheels will be moved in sympathy with each other to act upon an interposed envelop or the like and deliver said envelop upon the periphery of the folding-cylinder and thence into the folds of each paper as it is delivered to the folding mechanism within the cylinder and means to deliver the envelops to said tapes as and for the purpose set forth.

3. The combination with mechanism of a press adapted to receive and fold a paper web; of stack-holding devices, a rockin shaft, fingers upon the shaft adapted to engage and remove a portion of the stack only when said fingers arc'rnovediin one direction, a carrier for receiving said portions from the fingers and delivering them to the foldin mechanism and upon the paper web, an means in the path of the stack portions for preventing the removal of more than one portion from the stack at a time. i

4. The combination with stack-holding devices; of rocking fingers thereunder adapted to engage and remove portions of the stack, a carrier for receiving said portions from the fingers, a ioldin and sent-off cylinder adepted to receive 5X6 paper web therebetween, and folding mechanism adapted to subsequently receive the web, said carrier ada ted to deliver stack portions between the fol ingcylinder and the web.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
